Last night, I was sitting at a stop light when my engine stuttered and shook, and the check engine light came on. When the light changed and I gently gave it gas, the car died. I shifted to neutral, and it started right up and ran just fine. The check engine light is still on. I pulled the codes from the OBD unit, and got a 1-1-3, fuel injection problem. That was the only stored code. I checked both grounds and the four electical connections for corrosion, and all appear clean. The car continues to run without issues, except the light is still on (the OBD will not clear). Any suggestions? Thanks! Allen
